Inspired of all your great pics of "Divers with leather straps" I finally managed to have one myself.
My rebuild of the wonderful Citizen "Autozilla".
Java Rock Python and Titanium buckle from eBay'er Pstrapusa
Titanium Suppa adapters from Suppaparts.
Make the wearing of the watch a quite different experience. The Python strap is soft as butter and feels very nice on the skin. Very happy
